Comparative evaluation of virtual reality distraction and counter-stimulation on dental anxiety and pain perception in children

Equity implications of extended reality technologies for health and procedural anxiety: a systematic review and implementation-focused framework

OBJECTIVES

Extended reality (XR) applications are gaining support as a method of reducing anxieties about medical treatments and conditions; however, their impacts on health service inequalities remain underresearched. We therefore undertook a synthesis of evidence relating to the equity implications of these types of interventions.

MATERIALS AND METHODS

Searches of MEDLINE, Embase, APA PsycINFO, and Epistemonikos were conducted in May 2023 to identify reviews of patient-directed XR interventions for health and procedural anxiety. Equity-relevant data were extracted from records (n = 56) that met these criteria, and from individual trials (n = 63) evaluated within 5 priority reviews. Analyses deductively categorized data into salient situation- and technology-related mechanisms, which were then developed into a novel implementation-focused framework.

RESULTS

Analyses highlighted various mechanisms that impact on the availability, accessibility, and/or acceptability of services aiming to reduce patient health and procedural anxieties. On one hand, results showed that XR solutions offer unique opportunities for addressing health inequities, especially those concerning transport, cost, or mobility barriers. At the same time, however, these interventions can accelerate areas of inequity or even engender additional disparities.

DISCUSSION

Our "double jeopardy, common impact" framework outlines unique pathways through which XR could help address health disparities, but also accelerate or even generate inequity across different systems, communities, and individuals. This framework can be used to guide prospective interventions and assessments.

CONCLUSION

Despite growing positive assertions about XR's capabilities for managing patient anxieties, we emphasize the need for taking a cautious, inclusive approach to implementation in future programs.

The effect of virtual reality versus standard-of-care treatment on pain perception during paediatric vaccination: Study protocol for a randomised controlled trial

AIMS AND OBJECTIVES

To study the effects of virtual reality (VR) on pain perception among a paediatric population while being vaccinated. We will also investigate the effects of VR on the fear experienced by children during the vaccination procedure, as well as parental satisfaction levels.

BACKGROUND

Many studies, for example, in the fields of oncology, dermatology or plastic surgery, have described the benefits of using VR to reduce the perception of pain among paediatric populations. These results are encouraging, but their main limitations were the small sample sizes they included or their methodological design.

DESIGN

This will be a randomised clinical trial.

METHODS

SPIRIT guidelines were followed to report this protocol, and we will use the CONSORT and CONSORT-EHEALTH guidelines to report the randomised clinical trial. The sample will comprise 148 children aged 3-14 years who will come for vaccination at the Tres Forques Health Center. The participants will be randomly allocated into intervention group (VR; n = 74) or (the control group standard-of-care; n = 74) at a 1:1 ratio. The intervention group will view experiences with a VR headset as a distraction measure. The study variables will be the level of pain and fear perceived by the child during vaccination, parental satisfaction with the vaccination procedure, and sociodemographic and vaccination variables.

RESULTS

The start of the study is planned for September 2020, and the results will be expected in September 2021.

CONCLUSIONS

This study aims to identify what measures reduce pain and fear in children during vaccination, which in turn, can help to improve the degree of parental satisfaction with these procedures.

RELEVANCE TO CLINICAL PRACTICE

Vaccination is an independent function of the nursing profession. Identifying which distraction measures reduce the perception of pain and fear in the paediatric population will not only improve children's experiences but will also improve the satisfaction of both parents and children, thus increasing the degree of compliance with the vaccination schedule.

Behavior Puzzle: Nonpharmacological Behavior Management

A child's dental visit may often be associated with dental fear and anxiety (DFA). Children with DFA may exhibit dental behavior management problems (DBMPs), which mostly manifest as disruptive behavior. Children displaying disruptive behavior are often more challenging to treat, require more chairside time, and can result in a stressful appointment for the child, parent, and even the dentist. Factors that are specific triggers for DFA need to be identified, and their behavior assessed. This would help the dentist modify the child's behavior using appropriate behavior management techniques (BMTs) to facilitate the delivery of quality dental care. This article is not meant to be dogmatic or serve as a rulebook or a legal document. It sheds light on some practical methods of assessment of child behavior and communication, the key concepts in behavior guidance. The authors have also attempted to compile the nonpharmacological BMTs used in current clinical practice with evidence from the Indian scenario. They have also shared some of their personal experiences gained in the process of guiding children's behavior in the dental setting over the past two to three decades.

Impact of Virtual Reality on Perception of Dental Pain Associated With Dental Scaling in Healthy Adults: A Split Mouth Design Randomised Controlled Study

AIM OF THE STUDY

The aim of the study is to investigate the effectiveness of virtual reality (VR) in mitigating pain associated with dental scaling procedures. Furthermore, the study aims to evaluate individuals' tolerance levels to VR during dental scaling sessions.

MATERIALS AND METHODS

A randomised split-mouth design study was conducted on 29 systemically healthy adult patients aged 18 years and above. Dental scaling was performed in two quadrants while wearing VR glasses, with the remaining quadrants undergoing the procedure without VR. The sequence of procedures was determined by random allocation. Patients were provided with VR glasses loaded with a mobile phone. After the procedure, patients were asked to complete a VR questionnaire. The primary outcome variables included pain scores with and without VR, while secondary variables included VR experience scores, baseline heart rate (HR), difference in HR, systolic blood pressure (BP), diastolic BP, difference in systolic BP, and difference in diastolic BP.

RESULTS

All 29 subjects successfully completed the study. Paired analysis of outcome variables with and without VR glasses revealed a statistically significant difference in pain scores (two-tailed p < 0.001). Additionally, a strong positive correlation was observed between VR experience score and difference in pain score (γ = 0.78, p < 0.001). While positive correlations between modified dental anxiety scale (MDAS) score and pain scores were observed, they were not highly significant (without VR: γ = 0.31 p = 0.097, with VR: γ = 0.34 p = 0.072).

CONCLUSIONS

The VR environment significantly diminished pain perception during dental scaling. Participants who experienced the VR setting more positively reported an even greater decline in pain scores, highlighting the profound impact of immersive technology on patient comfort.

Evaluation of Effect of Distraction Techniques Using Virtual Reality and Eight-dimension Audio Analgesia Methods on Pain Perception and Anxiety Levels in Children During Restorative Procedures: A Comparative In Vivo Study

Introduction

Dental pain and dental anxiety are the most common determinants of negative dental experience, the reason for broken appointments and ignored oral health care affecting the quality of life.

Aim

To evaluate the effects of distraction techniques using virtual reality and eight-dimension (8D) audio analgesia method on pain perception and anxiety levels in children during restorative procedures.

Materials and methods

A total of 120 children between the ages of 4 and 10 years old who visited for the first time to a pediatric dental department were grouped equally between three interventional groups. Group I was treated with conventional tell-show-do (TSD) method; patients selected for group II (8D audio analgesia) and group III (virtual reality method) underwent two-step procedure that initially involved the TSD technique, by explaining the distraction techniques method conditioned for restoration treatment. Clinical evaluation of anxiety levels was measured by using the Chotta Bheem-Chutki (CBC), face, legs, activity, cry, consolability (FLACC) scale, and recording pulse and oxygen saturation rate. One-way analysis of variance (ANOVA) followed by post hoc Tukey's test was done to compare all the parameters between the three groups.

Results

In comparison to the conventional TSD method, both 8D audio analgesia and virtual reality method showed statistically better results. One-way ANOVA followed by post hoc Tukey's test showed no significant difference between the virtual reality group and 8D audio analgesic group.

Conclusion

Both 8D audio analgesia and virtual reality box distraction techniques can be used as an efficient distraction technique for TSD during dental procedures in children.

Analgesic Use of Virtual Reality for Burn Dressing Changes in Low- and Middle-income Countries: A Feasibility Study

Background

The paucity of pain management options in resource-limited settings is a significant and systemically unaddressed problem. To improve global health equity, it is important to bridge this gap in care without introducing the peril of opioid dependence. We present a proof-of-concept case series wherein virtual reality (VR) was successfully used to manage discomfort in patients undergoing burn dressing changes in sub-Saharan Africa.

Methods

Nine patients presenting with burn injuries of variable severity underwent routine stabilization and dressing as part of standard-of-care treatment. During dressing changes, a VR intervention consisting of the Dream Flight interactive game displayed on an Oculus Quest 2 headset was offered to patients. Patient mood scores were collected before VR initiation and at the conclusion of the dressing change by a translator using the Youth Feelings Scale.

Results

There were no adverse events associated with use of the VR headset and no patients elected to terminate the VR during their procedure. Patients and physicians subjectively reported satisfaction with the device's utility in the procedure. Before VR initiation, the 95% confidence interval for patient mood score was 4.89 ± 1.725. After VR initiation, the 95% confidence interval for patient mood score was 8.78 ± 1.40.

Conclusions

Our results of this proof-of-concept case series to suggest both feasibility of use and positive influence on patient discomfort and periprocedural satisfaction. We propose that VR should be explored as an analgesic alternative and/or adjunct to narcotics in resource-limited countries, particularly for high-pain, low-duration procedures.

Non-pharmacological interventions for reducing dental anxiety in pediatric dentistry: a network meta-analysis

BACKGROUND

Child dental anxiety is a prevalent issue in the field of pediatric dentistry. At present, several non-pharmacological interventions are employed to mitigate anxiety during dental treatments for children. The objective of this study is to assess the effectiveness of diverse non-pharmacological interventions in reducing dental anxiety, as well as enhancing heart rate during pediatric dental treatments. To achieve this, we conducted a systematic review and a network meta-analysis (NMA) to compare the efficacy of various outcome indicators.

METHODS

A thorough search was conducted in the databases of PubMed, Embase, Web of Science, Cochrane Library, Scopus, APA PsycInfo, CINAHL, and AMED to identify all eligible randomized controlled trials (RCTs) from the beginning of the databases up to August 1, 2024. The quality assessment was carried out using the Cochrane Collaboration's bias risk tool. The two outcome measures under consideration were dental anxiety and heart rate. Network graphs, league tables and SUCRA were constructed using R 4.2.3 software and Stata 16 software. This study is registered in PROSPERO under the registration number CRD42023467610.

RESULTS

The study examined 12 different non-pharmacological approaches, drawing from a pool of 61 research studies involving 6,113 participants aged 4 to 16 years. The results of the network meta-analysis revealed that music (SUCRAs: 93.60%) proved to be the most effective measure in mitigating dental anxiety, followed by aromatherapy (SUCRAs: 78.58%) and game (SUCRAs: 70.99%). Moreover, hypnosis (SUCRAs: 98.80%), music (SUCRAs: 79.58%), and relaxation (SUCRAs: 72.41%) were identified as the top three interventions for decreasing heart rate.

CONCLUSION

In this NMA, when contemplating dental anxiety outcomes, music is recommended as a priority. For heart rate outcomes, hypnosis may be a preferred measure. However, owing to the limited number of articles, the conclusion of this study still requires additional confirmation or correction through more high-quality primary studies in the future.

Recent Developments in the Non-Pharmacological Management of Children's Behavior Based on Distraction Techniques: A Concise Review

Oral diseases and conditions affect children's oral health and negatively influence their overall health. Early detection and intervention are important in mitigating these negative consequences. However, dental fear and anxiety (DFA) regarding dental procedures often hinder children from seeking necessary dental care. Non-pharmacological behavior management strategies, such as distraction techniques, are commonly adopted to manage children's behaviors. Distraction techniques have been developed rapidly in recent years and are widely accepted by both health professionals and parents due to their noninvasive and low-cost nature. This concise review aims to summarize current distraction techniques applied during dental treatments, especially for children. The most commonly reported techniques for children are audio distraction, audio-visual distraction, tactile distraction, olfactory distraction, and gustatory distraction. Audio distraction techniques involving music and storytelling help children relax. Audio-visual distraction techniques help to divert children's attention from the dental treatment. Tactile stimuli can reduce the transmission of pain signals. Olfactory stimuli can help children feel comfortable and relaxed. Gustatory distraction involving sweet substances can create a positive environment. These distraction techniques effectively reduce DFA in children and improve their satisfaction with dental procedures. As technology continues to develop, further research is needed to provide more robust, evidence-based guidance for dentists using distraction techniques.

Effect of Virtual Reality and Musical Earplug Temporal Tap Technique in Reduction of Gag Reflex in Pediatric Patients

Background

Gagging is a stimulated, protective reflex to prevent any material from entering the mouth or oropharynx. However, a hyperactive gag reflex is a common occurrence and anxiety-provoking stimulus while performing routine clinical procedures. Impression making is a clinical procedure that causes pronounced gagging and severe discomfort to the patient. As making an impression is a crucial step in routine dental treatment, it is imperative to make the process of impression making as comfortable as possible to provide quality dental care. Very few studies have reported on the effect of virtual reality (VR) and musical earplug temporal tap technique (METTT) in impression making.

Objectives

To evaluate the effect of VR and METTTs on the reduction of the gag reflex in pediatric patients.

Materials and methods

Sixty healthy patients aged 6-12 years were diagnosed with the presence of a hyperactive gag reflex using the Gag Severity Index (GSI). GSI scores of 2 and above were included in the study, and mandibular alginate impressions were made with standard distraction methodology, which served as the baseline level of gag in each patient. These children were then randomly divided into two groups. In the first group, 30 patients' maxillary alginate impressions were made with VR facilitated techniques, while the remaining 30 patients' impressions were made with the METTT. The amount of gag reduction was evaluated with the Gag Prevention Index (GPI) score during the impressions at intervals of 0, 30, and 60 seconds. Anxiety was assessed using heart rate, oxygen saturation, and the modified version of the faces dental anxiety scale following impression making.

Results

Intragroup METT-facilitated impression-making showed a statistically significant reduction in heart rate. However, intergroup comparison showed no statistically significant difference in the amount of reduction of the gag reflex, oxygen saturation, or patient experience.

Conclusion

The gag reflex was not reduced by VR or METTT. Nevertheless, a decrease in heart rate during METTT-facilitated mandibular impression making indicated a reduction in anxiety. Hence, METTT can be applied as an adjuvant in patients with severe gag reflexes when making an impression.

Efficacy of kaleidoscope, virtual reality, and video games to alleviate dental anxiety during local anesthesia in children: a randomized clinical trial

Background

Distraction is a technique used to divert a patient's attention from unpleasant procedures. This study aimed to evaluate the effectiveness of kaleidoscopy, virtual reality, and video games in reducing anxiety and pain during invasive dental procedures in children.

Methods

Sixty-six children aged 6 to 9 years were randomly assigned to three groups during local anesthesia administration: Group 1 (kaleidoscope), Group 2 (virtual reality), and Group 3 (mobile video games). The anxiety of the children was evaluated using physiological measures (heart rate) at three different time points: before, during, and after the procedure. The Raghavendra, Madhuri, and Sujata pictorial scale was used as a subjective measure before and after the procedure. Subjective measures of pain were assessed using the Wong-Baker Faces Pain Scale. The data were statistically analyzed using the Kruskal-Wallis and Wilcoxon signed-rank tests.

Results

In the intergroup comparison, there were no statistically significant differences in the physiological measures of anxiety scores between the three groups before, during, and after distraction. Raghavendra, Madhuri, and Sujata pictorial scale scores were assessed before and after distraction, but no statistically significant differences were observed. Among the three groups, the children in Group 2 showed a significant reduction in pain scores.

Conclusion

Compared with kaleidoscopes and video games, virtual reality is a promising distraction technique for reducing dental fear, anxiety, and pain during local anesthesia administration in children.

Effectiveness of Two Types of Distraction Techniques in the Management of Pain and Anxiety during Dental Treatment in 6-9-year-old Children

Aim

To determine the effectiveness of distraction with virtual reality (VR) distraction devices in comparison with mobile phone video games in the management of pain and anxiety during dental treatment in 6-9-year-old children.

Materials and methods

It was a comparative observational study. A total of 33 children aged 6-9 years who reported to the department for their first dental visit were selected and the subjects were divided into three groups. Group I patients were in a normal clinical environment without any distractions. Group II patients were given mobile phone video games. Group III patients were given a VR distraction device as a means of distraction.The anxiety levels of patients before treatment, after using a distraction device preoperatively, during local anesthesia injection, and after dental treatment were assessed. Pain after local anesthesia injection in each group was assessed. The easability of handling the patient and carrying out the procedure was assessed using a questionnaire. All data were collected and analyzed.

Results

The results showed when compared to the children in groups I and II, children in group III obtained significantly lower anxiety scores after treatment, and they also reported significantly decreased pain perception during dental treatment (p < 0.001). The pain while administering local anesthesia was greater for the control group and lowest for the VR group. It was observed that VR group patients were easier to handle and easier to carry out procedures than those in the mobile phone group.

Conclusion

Virtual reality distraction is an effective distraction technique for reducing pain and anxiety in children during various treatment procedures.

Clinical significance

Virtual reality distraction can be used effectively in clinics.It is a patient-friendly technique and is more comfortable for both patients and dentists during treatment.It does not require any previous education and training and has a positive impact on memories of the treatment, leading to behavior modification.

Comparative Evaluation of the Effectiveness of Innovative Periorbital Eye Massager and Virtual Reality Eyeglasses for Reducing Dental Anxiety during Dental Restorative Procedures in Children

Background

Many behavior management techniques are employed to reduce the anxiety associated with dental procedures in children. One of the most commonly used methods comprises audiovisual distraction using virtual reality (VR) eyeglasses. In this study, an innovative device, a periorbital eye massager (PEM), is compared with VR to evaluate dental anxiety in children.

Materials and methods

in this study, 22 children were divided into two groups, that is, group I consisting of PEM and group II consisting of VR. The participants were instructed to wear the device and then subjected to dental restorative procedures. After completion of the procedure, anxiety was measured using a validated questionnaire by the children and by using the modified behavior pain scale by the second investigator. Also, physiological parameters like heart rate and oxygen saturation were evaluated before and after a dental procedure.

Results

The results were statistically insignificant for group I and group II when a validated questionnaire and modified behavior pain scale were used to measure the dental anxiety of children. Also, the data also shows no significant difference in heart rate and oxygen saturation between the two groups.

Conclusion

The innovative PEM can also be used as an effective behavior management tool in managing dental anxiety in children, as there was no statistically significant difference between PEM and VR.

Clinical significance

As a pediatric dentist, the methods for administering a patient present a novel challenge because behavior management varies from patient to patient. As a result, the prospects for augmenting various techniques of behavior therapy for pediatric patients are limitless.

Effects of a Virtual Reality Game on Children's Anxiety During Dental Procedures (VR-TOOTH): Protocol for a Pilot Randomized Controlled Trial

BACKGROUND

Dental fear and anxiety (DFA) is a condition that affects approximately one-quarter of children and adolescents. It is a significant cause for pediatric patients to avoid dental care later in adulthood. Lack of patient cooperation due to DFA can create an environment of stress, often obligating dentists to end appointments prematurely and consider alternative pharmacological treatment options. Virtual reality (VR) use during dental care, providing an immersive experience through sensory stimuli, is potentially an additional nonpharmacologic tool to better manage DFA in children with special health care needs (SHCN) undergoing dental procedures.

OBJECTIVE

This pilot study aims to assess the feasibility and acceptability of VR immersion as a tool to reduce DFA in pediatric special needs patients undergoing dental procedures. The study also aims to gain insight on parent and health care provider perspectives on the use of VR during dental appointments.

METHODS

This pilot randomized controlled trial study will follow a parallel design including 2 groups: a control group (clinic's standard care using a wall TV) and an experimental group (using a VR game). We will randomize 20 participants to either group. Recruitment will be carried out at the dental clinic of the Centre Hospitalier Universitaire Sainte-Justine, a tertiary-quaternary care center that mostly serves pediatric patients with SHCN. The primary outcome will be patient recruitment rates and completion rates of planned procedures. DFA in children will be assessed using both an observation-based proxy assessment with the Venham Anxiety and Behavior Rating Scale and physiological assessments using parameters such as change in heart rate and levels of salivary alpha-amylase as a stress biomarker before and 10 minutes after the procedure. Sociodemographic characteristics, measures of the levels of parent and health care professional satisfaction, occurrence of side effects, and any deviation from normal procedure length will also be collected. Descriptive statistics, nonparametric tests, and effect sizes will be used for demographic and clinical variables and to present parent and health care professional satisfaction levels as well as procedural time.

RESULTS

This study will be conducted from May 2023 to May 2024, with results expected to be available in December 2024.

CONCLUSIONS

The pilot study will provide insight on the feasibility and acceptability of VR use in clinical dentistry to reduce DFA for pediatric patients with SHCN. This study will guide future research on VR use in pediatric dentistry and can serve as a framework for a larger randomized clinical trial.

Effectiveness of Virtual Reality Distraction on Pain Perception and Fear among Children with Cancer Undergoing IV Cannulation

Background

Cancer children are subjected to multiple cannulations during hospitalization. Pain and fear are most common during invasive procedures that are performed, especially IV cannulation, which can lead to worry. Exactly 25% of children are reported to have a fear of needle-related procedures. To examine the impact of virtual reality (VR) distraction on pain perception and fear in children with cancer undergoing IV cannulation.

Materials and Methods

Using a quasi-experimental design, 80 cancer children with IV cannulation between ages 7-18 were recruited to the intervention and control group (N = 40 + 40) using the purposive sampling technique. The virtual reality distraction device was used 10 min before the peripheral IV cannulation procedure and remained in place until the procedure was completed in the intervention group, and no device was used in the control group. Wong-Baker Faces Pain Rating Scale and Children's Fear Scale were used to assess the pain and fear of children and their mothers.

Result

Pain perception was found to be significantly lower in the VR distraction group among both children and mothers (1.82 ± 0.18, 8.01 ± 3.21) 95% confidence interval (CI) [0.82, 2.16] compared to the control group, respectively (P = 0.001**). Fear was found to be significantly lower in the VR distraction group among both children and mothers (0.81 ± 0.71, 3.01 ± 1.42) 95% CI [0.46, 0.91]. A strong positive correlation was found between children's and mothers' pain perception (r = 0.91, P = 0.001**) and fear (r = 0.84, P = 0.001**).

Conclusion

VR distraction can be used as an effective device in pain and fear management among children undergoing IV cannulation.

Managing Dental Phobia in Children with the Use of Virtual Reality: A Systematic Review of the Current Literature

BACKGROUND

It is common today to encounter anxiety in patients facing dental treatment. Virtual reality (VR) is presented as a high-performing and innovative procedure because it can distract patients undergoing dental procedures or prepare them for such treatments. In addition, this meta-analysis has gathered evidence on VR and its ability to reduce dental anxiety in pediatric patients undergoing different treatments.

METHODS

The major Scopus, PubMed, EMBASE and Web of Science databases were searched for scientific articles published up to 2023. Studies in which VR was used for children and adults as a measure against anxiety during dental treatments were included. VR was defined as a three-dimensional place where patients experience a sense of immersion as they find themselves in attractive and interactive environments that detach them from reality. Anxiety and pain were examined and measured during dental treatments in which VR was used by comparing them with standard care situations.

RESULTS

Twenty-five studies were identified, of which eleven met the inclusion criteria. The effect of VR was studied mainly in the pediatric population as a distractive method. Only two studies (not significant) on an adult population were considered.

CONCLUSIONS

this review shows that VR is an excellent distraction method that is effective in reducing anxiety before dental treatment; however, due to the few studies in this area, further research on VR as a tool to prepare patients for dental treatment is needed.

Effectiveness of virtual reality in reducing preoperative anxiety in adults: A systematic review and meta-analysis

AIM

To evaluate the impact of a virtual reality (VR) intervention on adult patients' preoperative anxiety, heart rate, respiration rate and blood pressure.

DESIGN

A systematic review and meta-analysis of randomized controlled trials (RCTs).

DATA SOURCES

A librarian-designed search of the Cochrane Library, PubMed, Web of Science, EMBASE, CINAHL, CBM, CNKI and Wanfang databases was conducted to identify research studies in English or Chinese on RCTs from their inception to 31 May 2022. Detailed search strategies and the checklist are provieded in Supplementary files S1 and S2.

REVIEW METHODS

Two researchers independently screened eligible studies. The Cochrane Handbook for Systematic Reviews of Interventions was used to assess the risk of bias in the included studies. A fixed- or random-effects meta-analysis model was used to determine the pooled mean difference based on the results of the heterogeneity test.

RESULTS

This study included 11 articles with a total of 892 participants. VR distraction comprised five studies, and VR exposure consisted of six studies. The results indicated that VR could reduce preoperative anxiety in adult patients and VR exposure seems to be more effective. The results also indicated that VR intervention can effectively reduce patients' heart rate and blood pressure compared to traditional intervention methods, but had no significant effect on respiration rate.

CONCLUSION

VR technology could relieve preoperative anxiety in adult patients through distraction or exposure. More well-designed RCTs containing a wider range of surgical types are needed to verify our findings before we can make strong recommendations.

IMPACT

Our systematic review and meta-analysis show a positive effect of VR distraction and exposure interventions in reducing preoperative anxiety in adult patients. We suggest incorporating VR into preoperative procedures as an auxiliary way to reduce negative emotions in eligible patients.

Pre-Treatment and Post-Treatment Dental Anxiety in Patients Visiting Intern Dental Clinic

Background and Objectives: This study aimed to assess the dental anxiety of patients using the modified dental anxiety scale (MDAS) questionnaire along with examining the possible relationship between dental anxiety and sociodemographic factors. Materials and Methods: The MDAS questionnaire was used to assess the anxiety level of the patients which included a total of five questions and five options to respond to each question. MDAS questionnaire was filled out by all the patients before the dental treatment. After finishing the treatment, all the patients were given a post-treatment questionnaire to assess their anxiety levels after treatment. Descriptive statistics were performed for measuring the frequency of responses. Mann-Whitney U test was used to compare the anxiety between the gender. The chi-square test was used to identify the distribution of pre-treatment with gender and post-treatment questionnaire with gender and treatment modalities. Linear regression was used to identify the association between clinical variables and different levels of anxiety. Results: A total of 115 patients including 59 males and 56 females with a mean age of 35 ± 11.34 years were included in the current study. Female patients were significantly more anxious about dental treatment compared to male patients. Linear regression showed that age and gender have a significant association with the pre-treatment anxiety level; however, types of treatment is not associated with the MDAS. Anxiety levels decreased for the majority of the patients after the treatment and types of treatment did not show any differences with the post-treatment anxiety level. Conclusions: Age and gender play an important role in dental anxiety; however, types of treatment are not associated with pre-treatment and post-treatment dental anxiety.

Recent Advances in Local Anesthesia: A Review of Literature

Even if local anesthetic is still the mainstay of pain management in dentistry, research will keep striving for novel and effective pain management techniques. The majority of research efforts are focused on improving anesthetic medications, delivery systems, and related methods. There are more recent technologies available that can assist the dentist in providing better pain relief with fewer unpleasant injections and fewer negative adverse effects. The purpose of the current review of the literature is to compile evidence that will convince dentists to employ modern local anesthetics, as well as other methods and techniques to reduce patient discomfort while administering anesthesia.

Effect of virtual reality and music therapy on anxiety and perioperative pain in surgical extraction of impacted third molars

BACKGROUND

The objective of this study was to evaluate the effect of virtual reality (VR) and music therapy on anxiety and perioperative pain in patients undergoing extraction of impacted third molars.

METHODS

A total of 275 patients who had to undergo surgery for third-molar extraction participated in a randomized controlled trial and were divided into 3 parallel groups: music therapy intervention (n = 91), VR intervention (n = 93), and control (n = 91). The Spielberger State-Trait Anxiety Inventory and the visual analog scale of pain intensity were used as measurements in this study.

RESULTS

Patients in the music therapy and VR groups showed a greater reduction in anxiety level scores after third-molar extraction surgery (reduction in total anxiety in music group: 15.12; 95% CI, 13.16 to 17.08; Rosenthal r, 1.61; P < .001; reduction in total anxiety in VR group: 9.80; 95% CI, 7.66 to 11.95; Rosenthal r, 0.97; P < .001; reduction in total anxiety in control group: 9.80; 95% CI, 7.66 to 11.95; Rosenthal r, 0.97; P < .001). The intensity of pain after the intervention was lower in patients in the music therapy group than patients in the control group (P = .04). After the intervention, the music therapy and VR groups presented a significant decrease in systolic blood pressure (P < .05), diastolic blood pressure (P < .05), and heart rate (P < .05) compared with the control group.

CONCLUSIONS

These findings suggest that the use of music therapy and VR during third-molar extraction surgery reduces anxiety and improves the patient's physiological parameters.

PRACTICAL IMPLICATIONS

Implementation of these interventions (noninvasive, nonpharmacologic, economic) in the field of oral and maxillofacial surgery and dentistry could improve procedures performed under local anesthesia, improving the clinical experience of patients. This clinical trial was registered with the Australian New Zealand Clinical Trials Registry. The registration number is ACTRN12622000384752.

[Virtual reality glasses as a distraction aid and anxiety reduction in a 7-year-old girl who underwent a dental extraction procedure. Case report]

Virtual reality in Pediatric Dentistry has enormous potential, in the treatment of phobia of dental treatments, this technology is also promising, since it shows satisfactory results and in the surgical area it has a high potential for complex treatments, allowing predictable and safe results. However, future studies should have to establish technological standards with high data quality and in the development of applications approved for clinical routine. Distraction is a non-pharmacological pain management technique commonly used by Pediatric Dentists to control pain and anxiety. There are some new techniques that use audio and video stimulation and distract the patient by exposing him to three-dimensional videos. These techniques are called virtual reality audiovisual systems. The objective of this case was to evaluate the effectiveness of virtual reality glasses as a distraction aid to reduce anxiety in a 7-year-old girl who attends the pediatric dentistry office to perform a dental extraction procedure.

A Quasi-experimental of a Virtual Reality Content Intervention for Level of Comfort of Indonesian Cancer Patients

This study aims to determine the effect of virtual reality content on the comfort level of cancer patients. This study used a quasi-experimental non-equivalent control group design and was conducted on 60 cancer patients. The intervention uses the virtual reality content "My Comfortable Environment," which was developed based on Kolcaba's comfort theory. Comfort level was measured using the Shortened General Comfort Questionnaire. The Wilcoxon and Mann-Whitney U tests were used to determine the differences before and after the intervention within the group and between the study groups. There was a significant mean difference between pre-test and post-test in the intervention group with P < .000, Z = -4.785, and in the control group with P < .041, Z = -2.032. These results indicate that interventions with virtual reality content and guided imagery both affect the comfort level of cancer patients. However, if the test was conducted between groups, there was a significant difference between the intervention group and the control group with a P value of <.000. These results indicate that the virtual reality content intervention can significantly increase the level of patient comfort through modifying various aspects of patient comfort, especially environmental aspects.

Basic behavioral management techniques in paediatric dentistry: A systematic review and meta-analysis

OBJECTIVE

To systematically retrieve and assess studies regarding the effectiveness of basic behavioral management techniques (BMTs) in paediatric patients.

DATA SOURCES

Electronic and hand searches were conducted to locate Randomized Controlled Trials (RCTs) reporting on objective and subjective evaluation of anxiety and behavior of children up to 12 years of age. Data extraction and risk of bias evaluation, using the Cochrane risk of bias tool (RoB 2.0 Tool), were performed independently and in duplicate for all included studies. Mean differences and standard deviations were used to summarize the data from each study and meta-analyses were conducted with studies of limited heterogeneity.

STUDY SELECTION

A total of 708 papers were identified and screened, 122 retrieved for full text appraisal and 62 finally included. Results suggested that all basic BMTs have acceptable effectiveness on paediatric patients' anxiety, fear and behavior during dental treatment. Meta-analysis showed a statistically significant difference in favor of distraction for subjective anxiety using facial scale (Mean diff.: 2.78; 95% CI: -3.08, -0.53; p=0.005) and Modified Child Dental Anxiety Scale (Mean diff.: 12.76; 95% CI: -6.09, -4.47; p=0.001) and a non-significant difference for heart rate (Mean diff.: 1.70; 95% CI: -6.54, 0.46; p=0.09). Music significantly reduced heart rate when compared to a control comparator, underlining the superiority of the BMT (Mean diff.: 2.71; 95% CI: -3.70, -0.59; p=0.007).

CONCLUSIONS

Limited evidence about efficacy of one technique over another raises important issues on the topic for future research regarding the management of the child patient in the dental setting of the 21^st century.

CLINICAL SIGNIFICANCE

Behavioral management comprises a challenge for clinicians, who need to be familiar with a range of techniques to meet patients' needs at individual level and be flexible in their implementation. Appropriate technique should incorporate patients' personality and parents' active involvement, within the contents of the changes in modern societies.

Effect of Virtual Reality on Pediatric Pain and Fear During Procedures Involving Needles: Systematic Review and Meta-analysis

BACKGROUND

Virtual reality (VR) is used as a distraction measure during painful clinical procedures associated with the use of needles. These procedures include vaccinations, blood draws, or the administration of medications, which can cause children to feel increased levels of pain and fear.

OBJECTIVE

The objective of this study was to collect and analyze the current evidence regarding the effectiveness of VR as a tool to distract children from pain and fear during needle procedures as compared to that of standard techniques.

METHODS

A systematic review and meta-analysis was performed. We included randomized clinical trials (RCTs) or quasi-RCTs with participants younger than 21 years who underwent needle procedures in which the main distraction measure used was VR and where the main outcome measure was pain. The databases searched included the PubMed, Web of Science, Scopus, PsycINFO, CINAHL, and Cochrane libraries. In this systematic review, the studies were analyzed by applying the Critical Appraisal Skills Program guide in Spanish and the Jadad scale. In the meta-analysis, the effect size of the studies was analyzed based on the results for pain and fear in children.

RESULTS

From 665 unique search results, 21 studies were included in this systematic review, most of which reported low methodological quality. The study sample cohorts ranged from a minimum of 15 participants to a maximum of 220 participants. Ten studies were included in the meta-analysis. The global effect of using VR as a distraction measure was a significant reduction in pain (inverse variance [IV] -2.37, 95% CI -3.20 to -1.54; Z=5.58; P<.001) and fear (IV -1.26, 95% CI -1.89 to -0.63; Z=3.92; P<.001) in children in the experimental groups.

CONCLUSIONS

The quality of the studies was mostly low. The main limitations were the impossibility of blinding the participants and health care personnel to the VR intervention. Nonetheless, the use of VR as a distraction measure was effective in reducing pain and fear in children during procedures involving needles.

The State of Science in the Use of Virtual Reality in the Treatment of Acute and Chronic Pain: A Systematic Scoping Review

Previous reviews have reported virtual reality (VR) to be an effective method to treat pain. This scoping review examines the state of the science for VR and pain both generally and by pain type (acute and chronic) related to types of mechanisms, dosage, effectiveness, and adverse events (AEs). We searched online databases PubMed, Web of Science, PsychInfo, and CINAHL from 2010 to 2020 and included studies from peer reviewed journals that examined people with pain, (excluding pain-free participants) with a primary outcome measuring pain. We assessed studies for risk of bias using PEDro criteria. We described data through counts and percentages. Significant results were determined through P-values. We found 70 studies representing 4105 people; 46 acute pain studies (65.7%), 22 chronic pain studies (31.4%), and 2 (2.9%) "both." The most common VR mechanism was distraction (78.6%) then embodiment (17.1%). However, distraction was the mechanism for 97.8% acute pain studies while embodiment was more common for chronic pain (54.5%). Dosage of VR was inconsistently reported and varied considerably. VR treatment groups showed significant improvements in pain, particularly for intensity of pain (72.1%) and quality of pain (75.0%). Few studies examined AEs. Limitations of this review include only examining last 10 years of articles and that many studies were missing data. VR appears to be an effective intervention to address both acute and chronic pain. Research evaluating VR mechanisms, dosage, and AEs is warranted, as is further work in under-served populations (children for chronic pain and older adults) as the current evidence is largely limited to adult populations with pain.

Psychological behavior management techniques to alleviate dental fear and anxiety in 4-14-year-old children in pediatric dentistry: A systematic review and meta-analysis

Child's uncooperative behavior can impede the efficient delivery of dental care. Therefore, in spite of exceeding availability of behavior management techniques there is a need to search for a psychological behavior management technique that effectively reduces fear and anxiety during dental treatment and instill a change in child's attitude toward the treatment and is also acceptable by the parents. The aim of our systematic review is to determine the efficacy of various psychological behavior management techniques in managing a child's behavior in pediatric dentistry by assessing the fear and anxiety levels, ease of use by the clinician, application in various operative procedures, and parental acceptance. A systematic search was conducted by two reviewers in databases PubMed, Google Scholar, Scopus, Web of Science, and Cochrane for the studies published from January 1, 2011, to December 31, 2020. Studies included were clinical studies which evaluated the efficacy of various psychological behavior management techniques by evaluating the fear and anxiety levels and the changes in behavior during dental treatment in children aged between 4 and 14 years. The studies selected were then assessed for quality with the help of predetermined criteria which categorized the studies into high, medium, and low. Through search strategy, 7147 articles were yielded. After screening through titles and abstracts, 60 nonduplicated articles were selected which were further screened for full text. At the end, 15 articles were included in systematic review and 3 articles for meta-analysis. It was concluded that all the psychological behavior management techniques aided in reduction of fear and anxiety. In noninvasive procedures, conventional psychological behavior management techniques can be effective but in invasive procedures other newer psychological behavior management techniques showed better results. The aspect of parental acceptance regarding various techniques was not discussed in any of the included studies.

The Effect of Breathing Exercise Using Bubble Blower on Anxiety and Pain during Inferior Alveolar Nerve Block in Children Aged 7 to 10 Years: A Crossover Randomized Clinical Trial

Introduction. The aim of this study was to evaluate the effect of breathing exercise using bubble blower on anxiety and pain during inferior alveolar nerve block (IANB) in children aged 7 to 10 years. Materials and Methods. In this randomized crossover clinical trial, thirty-five children with moderate to severe anxiety requiring bilateral pulp therapy of mandibular primary molars were enrolled. Based on random lists, 18 children received the BE + IANB and 17 children received a routine IANB at the first session. This trend became reverse at the second visit for each child. Anxiety was measured using Facial Image Scale (FIS), blood pressure, and pulse rate. Face Leg Activity Cry Consolability (FLACC) scale and Wong–Baker Facial Pain Scale (WBFPS) were used for pain measurement. The Paired Samples Test, Wilcoxon Signed Rank Test, and Interclass Correlation Coefficient were used for data analysis. Results. The means of FLACC, WBFPS, FIS, blood pressure, and pulse rate were higher at the control visit. However, these differences were statistically significant only for FLACC scale and WBFPS ( $P$ value <0.05). In subgroup analysis, only girls and children without any previous dental treatment showed significant differences in FLACC scale and WBFPS between the control and bubble blower side ( $P$ value <0.05). Conclusion. Breathing exercise using a bubble blower may be an efficient distraction and relaxation method to decrease pain of 7- to 10-year-old children with moderate to severe anxiety during inferior alveolar nerve block. However, anxiety levels were lower when applying BE, and the differences were not statistically significant.

Comparative evaluation of the effectiveness of two innovative methods in the management of anxiety in a dental office: a randomized controlled trial

Background

The first dental experience is vital in molding a child's attitude towards dentistry and dental outcomes. The cooperation of a child during dental treatment is essential to render successful and high-quality treatment. Dental anxiety is common in children undergoing dental treatment. The success of pediatric dental treatments and patient comfort depends on controlling the levels of patient anxiety in clinical settings. This study aimed to compare the effectiveness of the recorded maternal voice and virtual cognitive tool (Roogies application) in the management of pediatric dental patients.

Methods

The study was carried out with children aged of 4-7 years [n = 80, (40 male and 40 female)], without any past dental history, and were randomly allocated into two groups. After informed consent was obtained, the entire procedure was explained to the parents. Anxiety was assessed pre-, during, and post-treatment by measuring pulse rate, and recording Venham Picture Test (VPT) scores. Group A [n = 40; 20 boys and 20 girls)] was provided with a headphone that played a recorded maternal voice. Group B [n = 40; 20 boys and 20 girls)] was administered the virtual cognitive tool. After conditioning the children, oral prophylaxis was performed for both groups. A comparative evaluation was conducted for each treatment session.

Results

The intra-group comparison of VPT scores and heart rate for patients assigned to the recorded maternal voice showed a statistically significant difference in dental anxiety (P-value ≤ 0.001).

Conclusion

This study demonstrated that a reduction in dental anxiety with the help of recorded maternal voice forms an important component of non-pharmacological behavior management. Alternatively, the use of a virtual cognitive tool as an anxiety-reducing technique can also be advocated.

Using Virtual Technology for Fear of Medical Procedures: A Systematic Review of the Effectiveness of Virtual Reality-Based Interventions

BACKGROUND

Innovations in virtual reality (VR) technologies have improved the adaptability of its use in therapeutic settings, and VR has shown to be a promising treatment for fear of medical procedures, with research increasing in this area in recent years.

PURPOSE

This review aims to collate evidence for the impact of VR on fear of medical procedures.

METHODS

CENTRAL (Cochrane), MEDLINE, EMBASE, and PsychINFO databases were searched up to October 2020. A mix of experimental and case-control studies were included for review, which evaluated the effectiveness of VR for fear, anxiety, and pain of medical procedures for people with needle phobia, dental phobia, claustrophobia of medical scans, and burn wound care anxiety. Risk of bias (RoB) was assessed by Cochrane and ROBINS-I tools.

RESULTS

Twenty-eight studies were selected. Some studies included mixed participant groups of young people adults. The interventions varied, with VR used for distraction, hypnosis, or exposure. These were shown to be effective for reducing fear of medical procedures. However, effectiveness for blood-injection-injury phobias and burn wound care patients was unclear.

CONCLUSIONS

Evidence on the effectiveness of VR suggests that it does decrease fear of medical procedures in some situations. However, the RoB assessment illustrated a poor quality of studies across those included in this review, limiting the ability to draw firm general conclusions from the study findings. There is a need for further research exploring the use of VR technologies in the management of anxiety in physical health care settings.

Comparison of effectiveness of three distraction techniques to allay dental anxiety during inferior alveolar nerve block in children: A randomized controlled clinical trial

Background

Among the numerous methods used to control anxiety, distraction is the most popular method for controlling behavior during dental procedures in children. The present study aimed to use a fidget spinner, kaleidoscope, and virtual reality as distraction techniques individually and observe the effects on the anxiety levels of children subjected to inferior alveolar nerve block (IANB).

Methods

In this parallel-group randomized clinical trial, 102 children aged 6–9 years requiring IANB for various dental treatments were screened and 60 children who met the inclusion criteria were enrolled and randomly assigned into four groups of 15 each; Group 1 fidget spinner (FS), Group 2 kaleidoscope, Group 3 virtual reality (VR) and Group 4 no distraction (Control). The child's self-reported anxiety levels using Venham's picture test (VPT); the pulse oximeter was used to measure physiological signs of oxygen saturation and pulse rate at three intervals i.e. before, during, and after the IANB procedure. The collected data were statistically analyzed with SPSS 21 software. Paired t-test and One way ANOVA were used to compare the VPT, oxygen saturation, and pulse rate values.

Findings

Groups 1, 2, and 3 showed significantly lower mean VPT scores compared to Group 4. Groups 1 & 3 showed lower mean pulse rates and Group 2 showed comparable mean pulse rates to Group 4 respectively during the IANB procedure. Oxygen saturation levels remained non-significant between all the Groups (p > 0.05).

Interpretation

Fidget spinner, kaleidoscope, and virtual reality seem to be effective distraction methods and can be recommended as effective approaches to help alleviate children's dental anxiety during IANB procedures.

The effect of virtual reality on Children's anxiety, fear, and pain levels before circumcision

BACKGROUND

Circumcision is one of the oldest and most frequently performed surgical interventions in many societies across the world. Boys undergoing this procedure experience anxiety and fear during the preoperative period. In addition, postoperative pain in children is reported to be associated with anxiety and fear.

AIM

This study aimed to examine the effects of using virtual reality (VR) intervention before circumcision on the pre-and postoperative anxiety and fear levels and postoperative pain symptoms in children.

MATERIAL AND METHODS

This randomized controlled experimental study included 5-10-year-old boys referred to a pediatric hospital for circumcision between June and September 2019. Randomization was performed using the randomized block design, and the subjects were divided into control (n = 38) and experimental (n = 40) groups. The data were collected using a participant information form, the children's fear scale (CFS), the children's anxiety meter scale (CAM-S), and the Wong-Baker Faces Pain Rating Scale (WBS); data were analyzed using SPSS 22.0 package program.

RESULTS

Of the children included in the study, 59% were between the ages of five and six years and 78.2% had no previous hospital experience. Children in the experimental group had significantly lower mean scores of CAM-S and CFS in the pre-and postoperative periods than those in the control group. Also, the mean postoperative WBS score was significantly lower in the experimental group than in the control group.

DISCUSSION

Results of this study were similar to those reported previously that VR interventions were effective in reducing fear and anxiety in the preoperative period (Dehghan et al., 2019, Ryu et al., 2018; Olbrechta et al., 2020). Previous studies have shown that patient immersion in interactive VR provides a distraction from painful stimuli and can decrease an individual's perception of the pain (Pouarmand et al., 2018; Chad et al., 2018).

CONCLUSION

Distracting children using a VR intervention before circumcision decreased their anxiety and fear both before and after the surgery, and it was found that the pain symptoms were lower in the postoperative period.

Comparative evaluation of efficacy of external vibrating device and counterstimulation on child's dental anxiety and pain perception during local anesthetic administration: a clinical trial

Background

This study aimed to evaluate the efficacy of external vibrating devices and counterstimulation on a child's dental anxiety, apprehension, and pain perception during local anesthetic administration.

Methods

This was a prospective, randomized, parallel-arm, single-blinded interventional, clinical trial. One hundred children aged 4–11 years, requiring pulp therapy or extraction under local anesthesia (LA), were recruited and allocated equally into two groups (1:1) based on the interventions used: Group BD (n = 50) received vibration using a Buzzy® device {MMJ Labs, Atlanta, GE, USA} as a behavior guidance technique; Group CS (n = 50) received counterstimulation for the same technique. Anxiety levels [Venham's Clinical Anxiety Rating Scale (VCARS), Venham Picture Test (VPT), Pulse oximeter {Gibson, Fingertip Pulse Oximeter}, Beijing, China)] were assessed before, during, and after LA administration, while pain perception [Wong-Baker Faces Pain Rating Scale (WBFPS), Visual Analogue Scale (VAS)] was evaluated immediately after injection. Statistical analysis was performed using the Student's t-test to assess the mean difference between the two groups and the repeated measures ANOVA for testing the mean difference in the pulse rates. Statistical significance was set at P < 0.05.

Results

Significant differences in mean pulse rate values were observed in both groups. In contrast, the children in the BD group had higher diminution (P < 0.05), whereas the mean VCARS and VPT scores were conspicuous (P < 0.05). Based on the mean WBFPS and VAS scores, delayed pain perception after LA injection was more prominent in the BD group than in the CS group.

Conclusion

External vibration using a Buzzy® device is comparatively better than counterstimulation in alleviating needle-associated anxiety in children requiring extraction and pulpectomy.

Behaviour and Anxiety Management of Paediatric Dental Patients through Virtual Reality: A Randomised Clinical Trial

Clinicians should appreciate the effectiveness of virtual reality (VR) headsets for managing both the anxiety and the behaviour of non-cooperative paediatric patients who require treatment over several dental appointments. The aim of this study was to assess the effectiveness of using a VR headset as a distraction for managing the anxiety and behaviour of paediatric patients during their dental treatment. Eighty patients, aged between five and ten years old and who required dental treatment over three or more appointments, were randomly allocated into two groups. One group used a VR headset during all their appointments, and the other one did not use any distraction technique. The patients were asked to take a Facial Image Scale Test during their first and last appointments to assess their level of anxiety. Additionally, the dentist completed the Frankl Test to quantify the child's behaviour at the beginning and the end of their treatment. The results obtained, both from the group using the VR headset and from the control group, were compared using the chi-square test. The use of a VR headset during dental treatment significantly reduced anxiety (95% of the children were happy) and improved behaviour (100% positive behaviour) as compared with the control group (40% and 57.5%, respectively). A VR headset can effectively distract a paediatric patient, helping to reduce anxiety and manage behaviour during dental treatment.

Addressing virtual reality misclassification: A hardware-based qualification matrix for virtual reality technology

Through its unique sensory synchronized design, virtual reality (VR) provides a convincing, user-centred experience of highly controllable scenarios. Importantly, VR is a promising modality for healthcare, where treatment efficacy has been recognized for a range of conditions. It is equally valuable across wider research disciplines. However, there is a lack of suitable criteria and consistent terminology with which to define VR technology. A considerable number of studies have misclassified VR hardware (e.g. defining laptops as VR), hindering validity and research comparisons. This review addresses these limitations and establishes a standardized VR qualification framework. As a result of a comprehensive theoretical and literature review, the hardware-based VR qualification matrix is proposed. The matrix criteria consist of (1) three-dimensional (3D) synchronized sensory stimulation; (2) degrees of freedom tracking; and (3) visual suppression of physical stimuli. To validate the model and quantify the current scale/diversity of VR misclassification, a 2019 sectional review of health-related studies was conducted. Of the 115 studies examined against standardized criteria, 35.7% utilized VR, 31.3% misclassified VR, 18.3% were considered quasi-VR, and 14.8% omitted critical specifications. The proposed model demonstrates good validity and reliability for qualifying and classifying VR. Key Practitioner Messages Virtual reality (VR) therapy has gained rapid empirical support, although many practitioners do not understand the difference between genuine and less-realistic VR variations. That has resulted from an evident lack of suitable criteria to define VR across a range of studies and protocols. Our proposed hardware-based virtual reality qualification matrix addresses issues to do with misclassification, via the introduction of standardised criteria. Applying the matrix to existing literature has revealed that more than 30% of VR studies use hardware that does not fit the high standards of rigour required for immersion in a simulated space. The model is a practical tool researchers and practitioners can use to quality and verify VR standards across research studies.

Meditation Monologue can Reduce Clinical Injection-Related Anxiety: Randomized Controlled Trial

Background.

Strategies to reduce anxiety prior to injection procedures are not well understood. The purpose is to determine the effect of a meditation monologue intervention delivered via phone/mobile application on pre-injection anxiety levels among patients undergoing a clinical injection. The following hypothesis was tested: patients who listened to a meditation monologue via phone/mobile application prior to clinical injection would experience less anxiety compared to those who did not.

Methods.

A prospective, randomized controlled trial was performed at an orthopedics and sports medicine clinic of a tertiary level medical center in the New England region, USA. Thirty patients scheduled for intra- or peri-articular injections were randomly allocated to intervention (meditation monologue) or placebo (nature sounds) group. Main outcome variables were state and trait anxiety inventory (STAI) scores and blood pressure (BP), heart rate, and respiratory rate.

Results.

There were 16 participants who were allocated to intervention (meditation monologue) while 14 participants were assigned to placebo (nature sounds). There was no interaction effect. However, a main time effect was found. Both state anxiety (STAI-S) and trait anxiety (STAI-T) scores were significantly reduced post-intervention compared to pre-intervention (STAI-S: p = 0.04, STAI-T: p = 0.04). Also, a statistically significant main group effect was detected. The pre- and post- STAI-S score reduction was greater in the intervention group (p = 0.028). Also, a significant diastolic BP increase between pre- and post-intervention was recorded in the intervention group (p = 0.028), but not in the placebo group (p = 0.999).

Conclusion.

Listening to a meditation monologue via phone/mobile application prior to clinical injection can reduce anxiety in adult patients receiving intra- and peri-articular injections. Registration:ClinicalTrials.gov NCT02690194

Computer-Controlled Local Anesthesia Complication: Surgical Retrieval of a Broken Dental Needle in Noncooperative Autistic Paediatric Patient

The article describes an unusual case of retrieval of 8 mm fragment of a broken 30-gauge 21 mm dental needle in a 6 y.o. noncooperative autistic male patient. The needle of a computer-controlled local anesthesia device was broken during an attempt to administer local anesthetic, in order to perform conservative treatment of teeth 55 and 54 by a pedodontist. Despite the fact that the patient was under nitrous oxide sedation, an unexpected movement of the patient occurred and resulted in needle breakage. Due to the lack of patient cooperation, the surgical retrieval of a broken needle was performed under general anesthesia as part of one-day surgery procedures. The purpose of the article is to emphasize careful decision-making in proper choice of dental instruments during treatment of noncooperative paediatric patients even under sedation and to suggest dentists to carry out treatment of such patients under general anesthesia.

Influence of parent-provided distraction and interactive distraction with a handheld video game on the child's responses during local anesthesia administration

BACKGROUND

To evaluate the influence of parent-provided distraction (PPD) and interactive distraction (ID) with a handheld video game (HVG) on the child's responses to local anesthesia (LA) administration during dental treatment.

METHODS

Children attending the department of pediatric dentistry were randomly selected and distributed to the two groups (PPD and an ID with HVG). Parents in the operatory and the principles of tell-show-do remained common in both the groups. Behavioral, physiological, and self-report measures of pain were estimated using the Face, Legs, Activity, Cry, and Consolability (FLACC) scale, pulse rate, as well as Iowa pain thermometer-revised (IPT-R) scale and compared for both groups correspondingly. The SPSS (standard statistical package) version 17.0 (SPSS Inc., Chicago, USA) was used for statistical analysis at the significance of P < 0.05.

RESULTS

A total of 30 children (15 in each group) aged 7-11 years participated in the study. There were no significant differences observed among boys and girls (P > 0.05). The independent t-test for the pulse rate showed no significant difference between the two groups (P > 0.05). Paired t-test for pulse rate in the PPD group showed a significant difference compared to ID with the HVG group (P < 0.05). The scores for FLACC and ID with HVG, showed a statistically significant decrease in scores recorded for ID with HVG, whereas the scores recorded for FLACC did not show any statistically significant difference.

CONCLUSION

Based on the study results, PPD would be the least distressful option, compared to the ID with HVG in children while administering LA.

Use of Virtual Reality for the Management of Anxiety and Pain in Dental Treatments: Systematic Review and Meta-Analysis

(1) Background: Dental treatments often cause pain and anxiety in patients. Virtual reality (VR) is a novel procedure that can provide distraction during dental procedures or prepare patients to receive such type of treatments. This meta-analysis is the first to gather evidence on the effectiveness of VR on the reduction of pain (P) and dental anxiety (DA) in patients undergoing dental treatment, regardless of age. (2) Methods: MEDLINE, CENTRAL, PubMed, EMBASE, Wiley Library and Web of Science were searched for scientific articles in November 2019. The keywords used were: “virtual reality”, “distraction systems”, “dental anxiety” and “pain”. Studies where VR was used for children and adults as a measure against anxiety and pain during dental treatments were included. VR was defined as a three-dimensional environment that provides patients with a sense of immersion, transporting them to appealing and interactive settings. Anxiety and pain results were assessed during dental treatments where VR was used and in standard care situations. (3) Results: 32 studies were identified, of which 8 met the inclusion criteria. The effect of VR in children was significant, both for anxiety (standardized mean difference (SMD) = −1.75) and pain (SMD = −1.46). (4) Conclusions: The findings of the meta-analysis show that VR is an effective distraction method to reduce pain and anxiety in patients undergoing a variety of dental treatments; however, further research on VR as a tool to prepare patients for dental treatment is required because of the scarcity of studies in this area.

Effect of warming local anesthesia solutions before intraoral administration in dentistry: a systematic review

BACKGROUND

The aim of the present systematic review was to evaluate and compare the efficacy of warmed and unwarmed local anesthesia solutions in reduction of pain during intraoral injection administration.

METHODS

PubMed, Ovid SP, and Cochrane Central Register of Controlled Trials were searched from publication years 1990 to 2020 with relevant MeSH terms. Studies were screened by titles and abstracts, followed by full-texts evaluation of the included studies.

RESULTS

A total of four studies were included in the systematic review. Outcomes evaluated were subjective and objective pain during administration of the warmed local anesthesia solution in comparison with the unwarmed local anesthesia solution. Among the four studies that evaluated the self-reported pain score, three studies showed significantly lower pain scores associated with warmed local anesthesia. Only two studies evaluated the observed pain score, and both of them reported a significantly lower pain reaction with the warmed local anesthesia solution.

CONCLUSION

Within the limits of this systematic review, warming the local anesthesia solution to body temperature (37℃) before administration seemed to reduce the discomfort during intraoral local anaesthesia administration, and more high-quality studies should be carried out to validate the same.

Pain levels were evaluated in four studies (n = 4), anxiety levels in three (n = 3) and anxiety and pain together in seven (n = 7). Our meta-analysis was based on ten studies (n = 10). The effect of VR was studied mainly in the pediatric population (for pain SMD = −0.82). In the adult population, only two studies (not significant) were considered. Conclusions: The findings of the meta-analysis show that VR is an effective distraction method to reduce pain and anxiety in patients undergoing a variety of dental treatments; however, further research on VR as a tool to prepare patients for dental treatment is required because of the scarcity of studies in this area.

Comparative evaluation of the effectiveness of a mobile app (Little Lovely Dentist) and the tell-show-do technique in the management of dental anxiety and fear: a randomized controlled trial

Background

Behavior guidance is a technique used to subdue inappropriate behavior by establishing communication that meets the needs of a child. This study aimed to measure the effectiveness of a mobile app (Little Lovely Dentist) compared to the tell-show-do (TSD) technique in managing anxious children during their first dental visit.

Methods

Fifty children (30 boys and 20 girls) without any past dental experience, aged from 7 to 11 years, were randomly allocated into either the dental app group or the TSD group. The pre- and post-operative anxiety of children who underwent prophylactic cleaning was assessed both physiologically and subjectively using a heart rate measurement and the RMS pictorial scale, respectively.

Results

The intragroup comparison of heart rate and RMS scores for children allocated to the dental app group was statistically significant (P value ≤ 0.001). However, a significant reduction only occurred in the RMS scores, but not the heart rate measurements, in the TSD group. Conversely, there was an increase in heart rates in the TSD group.

Conclusion

Educating the child prior to a dental procedure using a smartphone application such as Little Lovely Dentist can significantly alleviate the anticipatory anxiety and engage children in dental treatment during their first visit.
